SECTION VIII- External Wiring

Installation Compliance

All field wiring made during installation must
comply with:

National Electrical Code NFPA 70 and
any other national, state, provincial or
local codes or requirements.

In Canada, CSA C22.1 Canadian
Electrical Code Part 1, and any other
local codes.

ELECTRICAL SHOCK HAZARD.
Before making any electrical connec-
tions to the PRESTIGE Excellence, dis-
connect electrical power supply at the
service panel. Failure to comply can
cause severe personal injury or death.

Line Voltage Connections

1. Connect 120 VAC/15 amp minimum

power wire to the 120V terminal strip on
the wiring panel below the PRESTIGE
Excellence control module, as shown in
Fig. 20, page 29.

2. Route the incoming 120 VAC power wire

through the provided openings in the bot-
tom jacket panel.

3. The unit is provided with a service switch

located on the front panel, check local code
requirements for compliance.

If local electrical codes or conditions
require an additional service switch, the
installer must provide and install a fused
disconnect or 15 amp (minimum) service
switch.

Thermostat Wiring

Isolate 120V wiring from 24V wiring to
prevent any potential electrical “noise”.

1. Connect room thermostat or the end switch

(isolated contact only) of a relay control
panel to the 24V terminal strip on the
wiring panel below the PRESTIGE
Excellence control module, as shown in
Fig. 20, page 29.

2. For proper operation install the room ther-

mostat on an inside wall away from influ-
ences of heat and cold, i.e. water pipes,
areas of draft, lighting fixtures and fire-
places.

3. Set the thermostat anticipator (if applica-

ble) as follows:

Set for 0.2 amps when wired directly to
the Room Thermostat.

Set to match the total electrical power
requirements of the connected devices
when wired to zone relays or other
devices. Refer to the relay manufactur-
ers’ specifications and the thermostat
instructions for additional information
on the anticipator setting.

When making low voltage connections to
the PRESTIGE Excellence, ensure no
external voltage is present in the thermo-
stat circuits. If external voltage is pre-
sent, provide an isolated contact to pre-
vent damage to the boiler control.
